Strongest monster

The Strongest monster in RuneScape (based on combat level) is currently tied between Vorago and Yakamaru, both with a combat level of 10,000. Monsters that are not attackable, such as the Ferret of Doom, are not included.

While Telos, the Warden would technically be the strongest monster in RuneScape if fought in an encounter of 801% or higher enrage (which would give him a combat level of 10,010), it does not count as his base combat level is 2,000. It should also be noted that if he were to be fought at 4,000% enrage (the highest possible enrage), his combat level would be 42,000.
